The prices of water heaters vary widely, according to their type, features and energy-inefficient. Typically, the more expensive water heaters are also the ones providing higher energy savings.

Water Heaters Prices
Budget water heaters: some few hundred dollars;
Modern condensing gas water heaters:$1,000 to $8,000;
Heat pumps water heaters: $2,000 to $8,000;

Gas water heaters: Prices and Savings

Prices of condensing water heaters: $1.000-$3,000 (low-range) to $4,000-$8,000 (top stainless).

Prices of standard gas water heaters: $400-$500.

Savings: a difference of 30% in the Energy Factor (EF) of gas water heaters amount to about $100 in energy savings per household/year (in USA, according to data from ACEE).

Bottom line: expensive condensing water heaters, with an EF of 90%+, only become economically advantageous for large water heating loads.

Solar water heaters

Prices of thermosyphon solar water heating systems (mild and hot climates): $2.000-$3.000;
Prices of drainback and other solar water heaters for cold climates: $4.000-$5.000+.

Solar water heaters can provide energy savings of 80% in sunny climates. That makes the recovery of the investment relatively easy in such climates, all the more than the type of solar heaters for these climates are the least expensive.

The payback is typically to long in cold climates. See, on these issues:  Solar Water Heaters Guide and Prices Solar Water Heaters.

Electric water heaters

Traditional stand-alone electric water heaters are inexpensive, but their running costs can be high (often twice those of gas water heaters, depending on electricity rates).

New electric water heat pumps provide hot water at competitive prices, but the cost of the best units is on the $4,000-$5,000+ range.
